Hi Bob If the input is "Processing\ncomplete" and the match string is "Processing complete" then this will not be a match, but if your enumeration value is "Pattern\scomplete" it should be OK (and it will also match "Pattern complete"(. (I guess the "sometimes garbles whitespace inside text nodes" is just the commercial XML editor wrapping lines that could exceed a 'pretty' length.

Our customer is using a commercial XML editor and the editor's implementation of the DOM API sometimes garbles whitespace inside text nodes when serializing XML documents for the document's xml property. This causes schema validation errors when we send that serialization off to be validated against the document type's schema using lxml. The problem we have run into with lxml is that the message property of the error object which comes back in the schema object's error_log has altered the value being validated. So, for example, if the text content of an element in the serialized DOM is "Processing\ncomplete" and the value it was supposed to match in the enumerated valid values is "Processing complete" then the message attribute for the corresponding object in the error_log has Element 'ProcessingStatusValue': [facet 'enumeration'] The value 'Processing complete' is not an element of the set {'Ready for English peer review', 'Ready for English scientific review', 'Ready for English OCCM review', 'Ready for Spanish peer review', 'Ready for Spanish OCCM review', 'Ready for publishing', 'Ready for translation', 'Processing complete'}. In effect saying "the value 'Processing complete' does not match the value 'Processing complete'." Took a very long time for us to figure out that the error message was wrong, and that it should have said ... The value 'Processing\ncomplete' is not an element of the set .... -- Bob Kline https://www.rksystems.com mailto:bkline@rksystems.com _______________________________________________ lxml - The Python XML Toolkit mailing list -- lxml@python.org To unsubscribe send an email to lxml-leave@python.org https://mail.python.org/mailman3/lists/lxml.python.org/ Member address: paul_higgs@hotmail.com
